Taysom Hill out for the season with torn ACL-additional damage per Rapoport [Hill placed on Injured Reserve on 12/6]

There was a Bills player that broke his neck on a kick off during a pre-season game about 10 years ago. They did a procedure on the field that was experimental at the time that saved his life.
Kevin Everett. If I remember correctly the league banned the wedge on kickoffs after his injury.

Correct, and after Eric LeGrand’s injury a few years later, which also happened on a kickoff, then-Rutgers HC Greg Schiano began working on alternates to the kickoff to propose to the NFL (Schiano was hired by the Buccaneers in 2012). Schiano’s first kick teams coordinator at Rutgers? Darren Rizzi, whose modified kickoff proposal a decade later was accepted by the league.
